Just had a conversation with one of my psycho frummy bal tshuva friends. This guy goes to feel good lectures and listens to tapes, however, when it comes to learning halacha, looks like it's too boring for him. This is actually the same conversation, about the same topic and the same store I had with him last year. He wanted to get something to eat and asked me if I know of any places that are still open. I told him he can get sushi on avenue M or if not too lazy, drive to Shoprite. Shoprite is, I'm pretty sure, owned by a Jew and sells sushi under a good hashgocha. He tells me that he's not sure if the owner sold the chometz properly so you can't buy sushi there. What?! I tell him that, one, there's a good hashgocha there and two, sushi is not chometz, though soy sauce is. His reply is that the hashgocha is only there for the cooking and you can't trust them to make sure that the store sold chometz properly and that you can't buy sushi because chometz might not have been sold properly. No point arguing with this guy since he's not much interested in learning halacha, he loves chumras though, so I just left. Last year he said he wants to ask a Rabbi, same thing he said this year and same thing he'll say next year.
There are plenty of books and online sources for halacha. If you want to know, you can find out or you ask a rabbi or go to a shiur. What infuriates me is that these people don't know halacha, gonna argue with you because you're not a rabbi and apparently know nothing because of that and they're not gonna bother asking or finding out themselves. One happy thought is that for them, ignorance is not bliss. Out of their own stupidity and stubbornness they're going to make their own lives worse.
